| 概要 | K.Abe，S.Okuno，et al.［Belle Collaboration］, We report the results of a search for the rare baryonic decays B0 → p{p}, λ{λ}, and B+ → p {λ}. The analysis is based on a data set of 31.7×106 B{B} events collected by the Belle detector at the KEKB e+e- collider. No statistically significant signals are found, and we set branching fraction upper limits B(B0 → p{p})<1.2×10-6, B(B0 → λ{λ})<1.0×10-6, and B(B+ → p {λ})<2.2×10-6 at the 90% confidence level. |
